CLOCK-MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 252,589, dated January 17, 1882.

Application filed October 24, 1831.

(Model.)

' tion is to make afrrst-class timetrain withtvvo driving-wheels, all ar 1anged in a very compact form. I attain these objects by the mechanism illustrated in the accompanying dravvings, in which- Figure 1 is a frontelevation, and Fie. 2 is a bottom view.

The time-train herein illustrated is one that beats seconds, and the verge-wheel makes a revolution once a minute, so that the shalt a, on which it is Inounted, is also the shaft to which the second-hand is attached.

A A designate the tivo drivingwheels, both driven by springs, but maybe driven by weights, if desired, which springs or weights are attached in any ordinary manner, but so as to revolve the wheels in the direction indicated by darts in Fig. 1. Between these wheels I place the'shaft b,and upon said shaft I mount the intermediate pinion, c, with both of the driving-Wheels meshing into it. The power of the wheel A and its spring or weight will,

through this pinion c, be communicated to the wheel A and to the rest of the train. The wheel A meshes into the pinion d, mounted on the same shaft with the wheel B, and this wheel drives the remainder ot' the train. The shaft b, which bears the intermediate pinion, c, has the pinion f and wheel g secured to it upon the front side of the movement-plate, which wheel and pinion constitute a part of the ordinary dial -vvheels, the remainder of which are made up ot' wheels l: and m, meshing into fand g, and carrying respectively the hour and minute hands. Bythis arrange- Inent of the parts the clock has a retaining power to act while one spring is being wound. The driving-wheels, both acting simultaneously on the pinion c, hold the shaft b steadily in place, and the disposition of the dial-wheels makes room for the extra driving-wheel and brings the train into a very coin pact form for a clock-movement having wheels of the, same size.

I claim as my inventionrlhc time-train herein described, in which the two driving-wheels mesh into and are coilnected by the intermediate pinion mounted on the shaft which drives the dialwheels, whileone of said driving-wheels meshes into the next pinion in and drives the remainder of the train, substantially as described, and for the purpose specified.
